D-SUBMINIATURE CONNECTORS INFORMATION
Introduction
INDUSTRIAL
The D-subminiature is one of the most popular styles of connectors in the I/O category. It is used in
computer, telecom, datacom, medical, and test instrumentation applications as well as in the military and
aerospace fields.
Types of D-subminiature connectors manufactured by Cinch
Printed Circuit Board connectors:
• Vertical connectors for panel mounting with Dip Solder PC tails.
• Right-Angle connectors for board mounting with Dip Solder PC tails.
Connectors for cable assemblies or wire harnesses:
• Crimp and Poke.
• Solder Cup.
• Insulation Displacement (IDC) to terminate discrete wire.
• Wire Wrap.
How to read this section
The information pages provide standard data common to all D-subminiature connectors. These include:
•
•
•
•
D-subminiature contact arrangements - see page 4.
Panel mounting specifications/hardware - see page 5.
D-subminiature shell dimensions - see page 6.
PCB thickness chart and PCB layout dimensions - see page 7.
D-subminiature pages are grouped by series. A series is a family of connectors with a similar performance level.
Each series shares a set of features and specifications, from economical and commercial grade product to high-
reliability and military connectors. Each series begins with a page outlining general features and specifications of
connectors, followed by the pages on individual connectors with drawings or features specific to that connector.
Drawings reflect clarifications of dimensions not called out in the information pages of this catalog.
Accessories including backshells, junction shells, and hoods as well as hardware can be found on pages 34 thru
50.
Termination tooling for Cinch connectors can be found at the end of the D-subminiature catalog.

D-SUBMINIATURE CONNECTORS INFORMATION
Introduction
General Information
INDUSTRIAL
All connectors are intermateable with any Cinch D-subminiature of comparable pin count and density, or the
D-sub connector of any other manufacturer complying dimensionally with MIL-C-24308.
Solder terminations and boardlocks meet the requirements for solderability in accordance with MIL-STD-202,
Method 208.
DURABILITY
• Mated connectors are subjected to cycles of insertions and withdrawals specified on the catalog page. After the prescribed
cycles the connectors will meet the Cinch requirements concerning insertion withdrawal force, individual contact insertion-
withdrawal force, and contact resistance.
APPROVALS
• Most Cinch connectors have UL recognition and CSA approval; however, the specific approvals are listed on the individual
catalog pages.
CONTACTS
• Cinch connector contacts are generally offered in Gold Flash or 30μin. gold plating for commercial product, and 50μin. gold
plating for M24308 Series Military D-subminiature connectors.
• Cinch connectors utilize economical stamped and formed contacts and/or screw machine contacts for enhanced perfor-
mance.
• Standard density connectors utilize size 20 contacts.
METAL SHELLS
• Commercial-grade steel shells are usually available in zinc plating with yellow or clear chromate finish or tin plating.
• Tin-plated plugs have grounding indents.
• Military grade M24308 Series connector shells are generally steel cadmium plating and yellow chromate finish.
• Insulator materials are glass-filled polyester, glass-filled nylon, and diallyl phthalate.
The connectors are usually available in plugs and sockets in 9, 15, 25, 37, and 50 position sizes.

D-SUBMINIATURE CONNECTORS INFORMATION
Introduction
Printed Circuit Board Connectors
INDUSTRIAL
Cinch provides connectors in various footprints, contact diameters, and lengths in both vertical and right-angle
PC mount styles with dip solder tails.
Cinch PCB connectors have metal shells.
Connectors for Terminating Cable Wire
Wire Wrap connectors are available in two tail lengths for two-wrap and three-wrap terminations. The contact is
terminated by wrapping wire around it using a wire wrap gun. This connector is especially useful for prototyping
since the wire can be unwrapped and rewrapped if necessary.

the conductor wire. Crimp and Poke connectors can be selectively loaded to save labor and material cost.
Solder Cup connectors allow reliable long-term termination by soldering the wire directly into the connector
contact. Cinch Solder Cups accommodate up to 20 AWG wire.
